PAUL L. GEEK, or SAN JOSE, CALIFORNIA.

OIL-VAPOR-HEATING roncrr.

Application filed. November 14, 1916.

To all whom it may concern:

Be it known that 1, PAUL L. GEEK, a citizen of the United States, and aresident of San Jose, in the county of Santa Clara and State ofCalifornia, have invented a certain new. and useful Improvement inOil-Vapor- Heating Torches, of which the following is a specification.

My invention relates to an improvement in oil vapor heating torches, andthe objects of my invention are:

First, to produce an oil vapor heating torch that can be attached to anyfuel oil atomizer.

Second, to so construct an oil vapor heating torch that will produce byadjustment any degree of heat required of the same.

Third, to so construct an oil vapor heating torch that will produce therequired heat for bending steel plates, or expanding collars, orcouplings on large shafts where an expansion is required to remove saidcollars or couplings from said shafts.

Fourth, to provide an oil vapor heating torch that will generate therequired amount of heat for shrinking large or small collars, couplings,or propeller wheels upon their respective shafts, or for any otherpurpose Where an intense heat may be required.

I accomplish these objects by means of the oil vapor heating torchillustrated in the accompanying drawings, in which:

Figure 1 is a longitudinal view of my oil vapor heating torch assembled.

Fig. 2 is a sectional view on line AA of Fig. 1 showing nozzle andcombustion chamber attached thereto, with air and gas pipes in position.

Fig. 3 is an end view of Fig. 1 showing outlet of nozzle and combustionchamber.

Fig. 4 is a longitudinal section on line BB of Fig. 1 showing pipes andconnections in position.

Fig. 5 is an end View of the air and gas vapor distributer.

Fig. 6 is an end view of the air and gas vapor receiving connection.

Fig. 7 is a sectional view on line C@ of Fig. 4 showing casing and pipesin position.

Referring now to the drawings 1 designates the main casing through whichoil vapor pipe 2 and auxiliary air pipe 8 pass; said oil vapor pipe 2and auxiliary air pipe 3 are made an integral part of casing 11, bybeing welded to casing 1 as shown at 4, and to air and oil v p r re i er,5, a ho n at 6, said a and Specification of Letters Patent.

Patented July to, 1917.

oil vapor receiver 5 having opening 2 passing therethrough to opening 2;said air and oil vapor receiver 5 being connected to air and oil vapordistributor 7 by coupling nut 8, whichin turn connects nozzle casing 9to distributor 7, by threaded portion 10.

Connected to air and oil vapor distributer 7 by threaded portion 7 isoil vapor pipe 11 through which oil vapor is distributed under pressurefrom oil vapor pipe 2 and opening 2 in distributer 7, and through aplurality of openings 2 in said distributer 7 0 pipe opening 11 and tocombustion cham- Free air opening is shown at 12 in air and oil vaporreceiver 5, delivering free air through said receiver 5 and through airand oil vapor distributer 7 at 12 to pipe 13, said pipe 13 connectingwith air and oil vapor distributer 7 by threaded portion 14: adapted todeliver free air to combustion chamber 9*.

Oil vapor hose connection is shown at 15 connecting with union jointcoupling 16 by threaded portion 17, said union joint coupling 16connecting with .oil vapor pipe 2 by threaded portion 18, oil vaporunder pres sure being controlled by valve connecting with oil vaporpressure hose which in turn connects with an oil atomizer not shown.

Auxiliary air hose connection is shown at 19 connecting with union jointcoupling 20 by threaded portion 21, said union joint coupling 2Oconnecting with auxiliary air pipe 3 by threaded portion 22; said airbeing under pressure is controlled by valve connecting with air hose notshown.

Air is delivered to pipe 3 under pressure, and through opening 23 in airand oil vapor receiver 5 and to air and oil vapor distributer 7, thencethrough openings 24 in said oil vapor distributer 7 through a pluralityof openings 2t in distributer .7, through opening 24 in nozzle casing 9,and from said casing 9 to combustion chamber 9 said combustion chamber 9is made of sheet steel of the required thickness and of the shape shownin the drawings, the same being hollow having an outlet 25, throughwhich the heat is generated from the air and oil vapor mixture deliveredin said combustion chamber 9.

A plurality of free air openings 26 are shown in combustion chamber 9,adapted to increase the combustion therein, said combustion chamber 9being connected to nozzle casing 9 by neck 9*, is adjustable on saidnozzle casing, and held in place on nozzle casing 9 by set-screw 27.

I do not wish to confine myself as to size of my oil vapor heatingtorch, as the same may be made of any size suitable to the work requiredthereof.

Having thus described my invention,what I claim as new, and desire tosecure by Let ters Patent, is:

1. In an .oil vapor heating torch the combination of a main casing, anair pipe, an oil vapor pipe, said air pipe and said oil vapor pipe beingmade an integral part of said main casing, an air and oil vaporreceiver, 5 an air and oil vapor distributer, means by which said airand oil vapor receiver and said air and oil vapor distributer areconnected together, a nozzle casing, means by which said nozzle casingis connected to said air and oil vapor distributor, means by whichsaidair pipe is connected to said air and oil vapor distributer, acombustion chamber, and means by which said combustion chamber isattached to said nozzle casing, said combustion chamber being adjust:able on said nozzle casing, substantially as shown and described.

2. In an oil vapor heating torch the combination of a main casing, anair pipe, an

oil vapor pipe, said air pipe and said oil vapor pipe being madeanintegral part of said main casing, an air and oil vapor receiver, anair and oil vapor distributor, a nozzle casing, a combustion chamber, afree air opening in said air and oil vapor receiver ada ted to deliverfree air to and through said air and oil vapor receiver and through saidair and oil vapor (listributer to said combustion chamber, air pressurehose connections, means by which the same are connected with said airpipe, and means by which said air and oil vapor hose connections areconnected with said oil vapor pipe, a nozzle casing, means by which saidcombustion chamber is attached to said nozzle casing, and a plurality offree air openings in said combustion chamber ada )ted to increase thecombustion therein, su stantially as and for the purpose described.

v 3. In an oil vapor heating torch the combination of a main casing, anair pipe, an oil vapor pipe, said air pipe and said oil vapor pipe beingmade an integral part of said main casing, an air and oil vaporreceiver, an air and oil vapor distributor, a nozzle casing, acombustion chamber, a free air opening in said air and oil vaporreceiver adapted to deliver free air through said receiver and throughsaid air and oil. vapor distributor and. said nozzle casing to saidcombustion chamber, an outlet in said combustion chamber adapted todeliver the burning flame and heat therethrough, and a plurality of freeair openings in said coinbustion chamber adapted to increase thecombustion therein, substantially as and for the purpose described.

In testimony whereof, I aliix my sign ature in the presence of twosubscribing witnesses, this 8th day of November, 1916.
